Natural and synthetic chitin films, obtained from the same source were produced and their physicochemical properties were examined comparatively. Firstly, natural chitin film was obtained from elytra of an insect (Oryctes nasicornis L.) and purity of the obtained chitin film (degree of acetylation: 79±2%) was demonstrated by solid state C nuclear magnetic resonance (C NMR). Then, the synthetic film was produced by dissolving of natural chitin film in LiCl-DMAc. The obtained natural and synthetic films were characterized by AFM, TGA, DSC, FTIR, mechanical properties, light transmission and contact angle. The analyses result demonstrated that natural chitin film lost very important properties such as high thermal stability, transparency, nanofibrous nature, tensile strength, Young's modulus and hydrophobicity after transforming the synthetic film.
天然和合成的几丁质薄膜由同一来源获得，并对其理化性质进行了比较研究。首先，从昆虫（Oryctes nasicornis L.）的鞘翅中获得天然几丁质薄膜，并通过固态 C 核磁共振（C NMR）证明所获得的几丁质薄膜的纯度（乙酰化度：79±2%）。然后，通过将天然几丁质薄膜溶解在 LiCl-DMAc 中来制备合成膜。通过 AFM、TGA、DSC、FTIR、机械性能、透光率和接触角对获得的天然和合成膜进行了表征。分析结果表明，天然几丁质薄膜在转化为合成膜后失去了高热稳定性、透明度、纳米纤维性质、拉伸强度、杨氏模量和疏水性等重要性质。
